Hi Colin,
The plugs have a ball bearing in which you hammer/tap in to expand the plugs in the exhaust port, I've removed the unit and the pipes and just need to remove the inlet pipes from the exhaust ports, mine seem really tight and I don't want break anything. The front end has been neglected a bit by the previous owner and all bolt heads etc. are a bit corroded.
There's a few caps included for blanking off the vacuum hoses.
HELP !! Has anyone got any tips on removing these or how they are fitted into the exhaust ports? before I go for it!
Cheers John.
